Update - thanks for all your input. I sat down with my niece (she graduated from highschool in June) and we came up with a plan. The large flowers are appliqued onto 15" squares, the medium flowers are applicqued onto 10" squares to which I will add wonky borders until they are 15". I'll alternate the large and medium flower 15" blocks to make the quilt. Should be pretty funky looking. The left over flowers will be appliqued in a couple of rows onto a solid piece of gray to make a twin size quilt for her college dorm. So she'll have a queen size forever quilt and a twin size to use at college.
